AWS-DevOps-Engineer-Professional Exam Question 156

A company has a web application that uses an Amazon DynamoDB table in a single AWS Region to store user information. To support an increasingly global user base, the application must run in a secondary Region and allow users to connect to their closest Region and fail over to the secondary Region.
Which approach should be used to ensure the deployment meets these requirements?

A.Configure DynamoDB streams to copy data between Regions, deploy the web stack in both Regions, and configure Amazon Route 53 to use a geoproximity routing policy with health checks.

B.Convert the DynamoDB table to a global table, deploy the web stack in both Regions, and configure Amazon Route 53 to use a geoproximity routing policy with health checks.

C.Define DynamoDB cross-region backups to copy data to the secondary Region, deploy the web stack in both Regions, and configure Amazon Route 53 to use a latency-based routing policy with health checks.

D.Use DynamoDB Accelerator to copy data to the secondary Region, deploy the web stack in both Regions, and configure Amazon Route 53 to use a failover routing policy.

A company is deploying a container-based application using AWS CodeBuild. The security team mandates that all containers are scanned for vulnerabilities prior to deployment using a password-protected endpoint. All sensitive information must be stored securely.
Which solution should be used to meet these requirements?

A.Use the AWS Encryption SDK to encrypt the password and embed in the buildspec.yml file as a variable under the secrets mapping. Attach a policy to CodeBuild to enable access to the required decryption key.

B.Import the password into an AWS CloudHSM key. Reference the CloudHSM key in the buildpec.yml file as an environment variable under the variables mapping. Reference the environment variable to initiate scanning.

C.Store the password in the AWS Systems Manager Parameter Store as a secure string. Add the Parameter Store key to the buildspec.yml file as an environment variable under the parameter-store mapping.
Reference the environment variable to initiate scanning.

D.Encrypt the password using AWS KMS. Store the encrypted password in the buildspec.yml file as an environment variable under the variables mapping. Reference the environment variable to initiate scanning.

AWS-DevOps-Engineer-Professional Exam Question 158

You need the absolute highest possible network performance for a cluster computing application. You already selected homogeneous instance types supporting 10 gigabit enhanced networking, made sure that your workload was network bound, and put the instances in a placement group. What is the last optimization you can make?

A.Use 9001 MTU instead of 1500 for Jumbo Frames, to raise packet body to packet overhead ratios.

B.Segregate the instances into different peered VPCs while keeping them all in a placement group, so each one has its own Internet Gateway.

C.Bake an AMI for the instances and relaunch, so the instances are fresh in the placement group and do not have noisy neighbors.

D.Turn off SYN/ACK on your TCP stack or begin using UDP for higher throughput.

AWS-DevOps-Engineer-Professional Exam Question 159

Your system uses a multi-master, multi-region DynamoDB configuration spanning two regions to achieve high availablity. For the first time since launching your system, one of the AWS Regions in which you operate over went down for 3 hours, and the failover worked correctly. However, after recovery, your users are experiencing strange bugs, in which users on different sides of the globe see different data.
What is a likely design issue that was not accounted for when launching?

A.The system does not have Lambda Functor Repair Automatons, to perform table scans and chack for corrupted partition blocks inside the Table in the recovered Region.

B.The system did not implement DynamoDB Table Defragmentation for restoring partition performance in the Region that experienced an outage, so data is served stale.

C.The system did not include repair logic and request replay buffering logic for post-failure, to resynchronize data to the Region that was unavailable for a number of hours.

D.The system did not use DynamoDB Consistent Read requests, so the requests in different areas are not utilizing consensus across Regions at runtime.
